2,600-gallon liquid Hydrogen, 9,000 PSI Run Tank

This picture shows setting a 13.4-inch-thick stainless steel hemisphere prior to welding.
This picture shows the stainless steel inner vessel after welding. The 13.4-inch-thick girth weld was radiographed with a linear accelerator, as was the manway-to-sphere weld, which was only eight inches thick.
This picture shows the the vessel at the beginning of a boil-off test. Liquid Nitrogen is being pumped into the inner vessel. At this early stage, the liquid nitrogen is vaporizing very rapidly while cooling the four-inch-thick wall of the dewar's inner vessel from ambient temperature to -350 degrees Fahrenheit. Note the blue exhaust.
